Specification of Letters Patent.

Patented Oct. 3, 1905.

Application filed February 10, 190 1. Renewed March 8, 1905. Serial No. 249,122.

To all whom it may concern:

Be it known that I, JOHN H. HUHN, a citizen of the United States of America, residing at Gypsy, in the county of Harrison and State of IVest Virginia, have invented certain new and useful Improvements in Machines for Operating Coal-Angers, of which the following is a specification.

This invention relates to boring and drilling, and particularly to a device for cutting coal and stone in mining operations.

An object of this invention is to provide novel means for permitting the oscillation of the cutter and head and its standard, whereby a cut may be effectively reached from the floor around the ceiling and down to the floor on the opposite side of the head.

Furthermore, an object of the invention is to provide novel means for transmitting power to the drill and for periodically disconnecting the gearing and for throwing it into action by simple mechanism under the control of an operator.

Furthermore, an object of the invention is to provide novel means for bracing the standard and head at the varying positions thereof during their oscillation.

Finally, an object of the invention is to produce a device of the character described which will possess advantages in points of efiiciency and durability, proving at the same time simple in construction and comparatively inexpensive to manufacture.

ith the foregoing and other objects in view the invention consists in the details of con-' struction and in the arrangement and combination of parts to be hereinafter more fully set forth and specifically claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming part of this specification, wherein like characters denote corresponding parts throughout the several views, in which- Figure 1 is a view in elevation of a platform, partly in section, and a drilling apparatus applied thereto. Fig. 2 is a top plan view thereof. Fig. 3 is asection taken on the line 3 3 of Fig. 1,the standard and head being shown in elevation. Fig. at is a vertical sectional view of the device shown in Fig. 3. Fig. 5 is a detail view of the side and end of the shaft-bearing. Fig. 6 illustrates a front and side view of the shaft-adjusting device. Fig. 7 is a detail view of the means for feeding the drill. Fig. 8 is a fragmentary cross-section of the base, showinga part of the brace in elebase 2 and being provided with an end which is angular in cross-section receives the beveled gear-wheel 3, which rotates with the armature. The central portion of the base 2 has a boss C, through which the armature B projects and on which is rotatably mounted an arm D, which terminates at the edge of the base. The arm D is for the purpose of supporting and gearing the mechanism of the drill, and said arm is rotatable around the surface of the base.

Suitable brackets a extend upwardly from the arm and support a hub Z), in which the shaft 0 is mounted and is slidable. One end of the hub b is reduced, and said reduced portion 3/ is adapted to fit in an aperture in the inner bracket 0 and be supported on one of said hubs. The opposite end of the hub is provided with a collar w, having an enlarged and flattened body portion adapted to rest on the arm D and be secured thereto by a bolt or other means The object of this collar :15 is obvious. An annular flange w is formed on the hub, which, together with the shoulder formed by the reduced portion y, limits the movement of said hub within the inner bracket a. The outer surface of the hub at one end is provided with longitudinally-disposed ribs (Z, with which the cam c coacts, the said cam being in the shape of a ring fitted on the end of the hub and having recesses e, which are designed to receive the ribs (Z when the said cam is in one position, the said cam riding over the ends of the ribs when in another position, as shown in Fig. 1. The cam is designed to bear against the hub of the gearwheel 6, which gear-wheel is mounted on the shaft 0 and is rotatable therewith, and the said wheel 6 is designed tomesh with and be driven by the gear-wheel 3. The shaft 0 extends beyond the end bracket and has near its end a washer a thereon, held by a pin (4 The spiral spring 10 embraces the shaft 0 between the bracket and the washer and exerts suflicient pressure therebetween to throw the gear wheel 6 out of engagement with the gearwheel 3 when the cam is rotated with the ribs registering with the recesses.

The standard 0 is composed of two sections 0 and O The section O has a bifurcated lower end, and the two extensions f thereof are fitted between the brackets a, and said extensionsf' have bearings f, in which is journaled a sleevef', which carries a bcvel-gear f". The sleeve is rotated through the medium of the shaft 0, which shaft has shoulders c, which are caused to engage angular sockets f of the sleeve It will thus be seen that with the thrust of the shaft 0 the portions 0 of the shaft will be caused to engage and disengage the sleeve, so that said sleeve will be rotated or will remain at rest, according to the position of the said portion 0 of the said shaft. The means for controlling the shaft having been described as being accomplished by the operation of the cam, the upper .end of the section 0 is reduced, and litting over said reduced portion is the lower end of the section To secure the two sections together, a slit or cut-away portion 0 is provided in the endof the section 0 and projecting from the sides thereof are parallel lugs 1/, adapted to be engaged by the clampingscrew n, the operation of which will be clearly apparent.

The arm I) is held in different positions on the base by means of the set-screw E being threaded in the outer bracket (1.

The standard has suitable bearings for the vertical shaft F, which is driven through the medium of the gear-wheel F engaging the.

gear-Wheel f and the upper end of the shaft F has a gear-wheel G, which d rives the gearwheel H of the sleeve /1., the said sleeve having a feather 20, which engages the drill, so as to cause the rotation of the drill with the said sleeve it. The drill is fed through the medium of the split nut21, which has its two sections mounted on the pivot 2', extending into the head I. A lug J is formed integral with the head I, and a brace K is pivoted to the said lug. This part of the head and the brace being fully disclosed in a former application, Serial No. 167,76 I, and dated the 31st day of July, 1903, will not be described furtherin detail. The free end of the brace is turned downwardly, as at L, at approximately right angles to engage the sockets L in the base, so that the head I may be adjusted at varying angles and be moved from side to side and be braced regardless of its position.

The standard is trunnioned in the brackets a, and said brackets are provided with curved slots M, through which the binding-bolt N projects, the said binding-bolt being carried by the standard. The object of this boltN is to bind the standard at varying adjustments, as shown in Fig. 3, from which illustration it will be observed that the said standard may be oscillated from side to side, so as to bring the drill which is carried by the head of the standard down to the floor of the cut and up to the roof thereof, and the said bolt N permits the said standard to be secured in the several adjusted positions.

Having fully described the invention, what ard in varying positions, means for permitting the oscillation of the standard, a drill carried by the standard, and means for driving the drill.
